Abstract
Hoya sinagtala Brillo, Cabactulan & Rodda sp. nov. (Apocynaceae, Asclepiadoideae) from the Philippines is described. When sterile, it resembles several species of Hoya section Acanthostemma, but its flowers make it readily distinguishable by its rotate corolla with a narrowly campanulate tube and free-spreading lobes and triangular-ovate corona lobes. No other species in the genus exhibits this unique combination of characters. The species was originally collected from the wild in Samar Island and subsequently widely distributed in cultivation under the informal name Hoya sp. Samar GN 0003 and Hoya sp. “Yellow Sapphire”; it is herein formally published after nearly seven years of horticultural circulation.
